You forgot one scenario: the fed keeps the rate as it is. Which is what they've been doing since 2009, at almost 0 (zero) percent. They've been stealing from savers and forcing people to spend their money. Anyway, my point is, what the OP is saying has no bearing on btc price, since the fed is going to raise the rate in less than two weeks. It won't affect btc price much. There's zero connection between the fed's policy and btc. As far as the fed is concerned, btc might as well not exist.
A rate rise will certainly test bitcoin as an asset, not because of itself, but because a hike potentially has huge ramifications for the global economy.
If the reaction is *bad*, the way I can see a rate rise impacting on btc is that even an small rate rise should see a) outflows from EM's accelerate, back into the USD. EM's sell FX reserves and US treasuries, b) EM USD denominated corporate debt blow up as further currency falls + hike sees interest payable rise, c) junk bond yields rocket & defaults spike (already happening), d) bond markets get real worried (maybe a sovereign debt default somewhere? Turkey, Spain, Brazil?), e) stock markets dump, grasping that the start of a hiking cycle is *real* (cheap money is finished).
This is all deflationary for a US and global economy already fighting deflationary forces. All the incoming capital flows to the USD, making it stronger. Maybe this translates to a booming Dow Jones - the USD will have to park somewhere. In some of these cases btc might dump hard, but as an alternate asset, btc may recover & receive a trickle of cautionary (sidelined) money wishing to exit the fiat superhighway.
In the case of a rise, and the Yuan is further devalued (can remain constant while USD goes up) / capital controls tighten / China breaks peg from appreciating dollar, then perhaps btc will moonshot if you believe in a correlation between cap controls and btc price.
If they go for negative rates, it will only be for the banks to park reserves, not for the people (yet). They want to push banks to lend money, to get the velocity going. But you can't lend if no one wants to borrow.
So will be an interesting month. I think they will raise, for the sake of credibility. But then, they'll only just cut them again next year.
